g- 3, 1939- M. PATTERSON 47 SAFETY RAZOR Filed Dec 51, 1955 INVENTOR a I? I ATTORNEY Patented Aug. 8, 1939 PATENT OFFICE SAFETY RAZOR Morehead Patterson, New York, N. Y., assignor to Durham Duplex Razor Company, a corporation of New York Application December 31, 1935, Serial No. 56,882

4 Claims.

parts, Fig. l is a side view of a. device constructed in accordance with the invention; Fig. 2 is a front view of said device, as seen from the line 2- -2 in Fig. 1; Fig. 3 is a cross sectional view taken on the, line 3-3 in Fig. 2; Fig. 4 is .a face view of the clamp shown in Figs. 1 and 3; Fig. 5 is a face View of said clamp assembled with an Enders blade; and Fig. 6 is a face view of said clamp assembled with a Christy blade.

In carrying the invention into effect, there is provided a razor frame having a blade seat and provided with clamp holding means arranged angularly with respect to said seat and with means to prevent rearward movement of a blade and said clamp, and a clamp having spring engagement with said clamp holding means to: hold a blade between said seat and said clamp.

In the best constructions contemplated, the razor frame has clamp holding means or surfaces at both of its ends, and the clamp has spring lugs at both of its ends to engage said surfaces; the clamp lugs slidably engage the clamp holding means orsurfaces of the razor frame; and the clamp lugs are integral with its body portion, the clamp as a whole being normally flat when detached from the frame.

Referring to the drawing, which illustrates but one embodiment of the invention, the razor frame 1 has a blade seat 8 against which a blade 9 rests. The blade may be of the flexible Enders type shown at SE in Fig. 5, or of the non-flexible Christy type shown at 9C in Fig. 6, or of any other type suitable for use in the frame 1.

The frame I is also provided at each of its ends with clamp holding surfaces Ill arranged angularly with respect to'the blade seat 8. These surfaces are engaged by spring lugs I I formed on the ends of a clamp ill, the clamp being normally flat when detached from the frame. To avoid interference with the cutting edge of the blade used, the clamp I2 is narrower than said blade.

The frame 1 is also provided with ledges I3, I3

to engage the rear edge of the blade used and the clamp 12 to prevent rearward movement thereof when the device is in use.

To assemble the parts of the razor, a blade 9, 9E, or 90, is placed on the blade seat 8, and the clamp 12 is pushed down behind the blade until its rear edge snaps into engagement with the ledges l3, l3. As the clamp moves down, its spring lugs ll come into engagement with the clamp holding surfaces Ill and are flexed thereby to cause the clamp to hold the blade firmly between the blade seat .and the clamp. To take the parts apart, it is only necessary to withdraw the clamp from the frame, thus freeing the blade.

Changes and variations within the scope of the claims may be made in the structure by means of which the invention is carried into effect. The invention, therefore, is not to be restricted to the precise details of the structure shown and described.

What is claimed is:

l. The combination with .a razor frame fabricated throughout of substantially rigid material, and having a blade seat provided at its endswith rigid clamp-holding surfaces; of a blade; and a normally flat clamping member having at its ends integral spring lugs and engaging said surfaces slidably to hold the blade between said seat and said clamp, said spring lugs operating in conjunction with said holding surfaces to compensate for variations between blades of various shapes, and said blade seat having its material relieved at its medial portion to permit ready manipulation of the blade at itsrearward edge, for insertion, adjustment and removal.

2.'In a safety razor, the combination with a blade seat, of a blade positioned on said seat, a handle secured to said seat, and a flat clamp unsecured to said handle and having aresilient portion adapted to be flexed by engagement with said seat to hold the blade between the clamp and seat, without flexing the blade said resilient portion being normally disposed in the plane of the body portion of the clamp at the end thereof.

3. In a safety razor, the combination with .a blade seat provided with a slideway adapted to engage and flex a clamp, of a blade positioned on said seat, and a fiat clamp having a resilient portion adapted to be flexed by engagement with said way to hold the blade between the seat and clamp, the slideway being disposed obliquely of the blade seat, and said resilient portion being normally disposed in the plane of the body portion of the clamp.

4. In a safety razor, the combination with a blade to be held between said clamp and blade seat, said holder also being provided with ledges arranged to engage the rearward longitudinal edge of said clamp to prevent transverse displacement of the clamp and blade on the blade 5 seat, said tongues being disposed in the plane of the body portion of said clamp.
